There used to be lots of books on sprite engines. Most that I recall were actually using either a Doom engine or the Build engine (Duke Nukem 3d). Try googling BUILD ENGINE, looks like lots of info and possibilities there. That engine seemed more approachable than the doom engine, as I recall.

But more recently it's all been full 3D, and I haven't heard of anything recent in sprite tools. It's all been Ogre and then Unity, or mods for specific games.

Does it have to be one that runs in DOS? The ZDoom port of Doom has so many modding features that it could practically be considered a GCS these days, if you know how to use it. Check out Harmony or Urban Brawl for an idea of the sort of total overhaul that can be done with it.

A preview is that Quadko can edit it to make it use Microsoft and SONY controllers and such.

I don't know if this is something. However, you mentioned sprites and I made my own sprite system. This is a special edition since I have not updated it since a year ago or such.

Just edit xenon.bmp and you have your new sprite you could move around. Please use the W A S D key for movements.

For those of you who are aspiring game makers, I challenge you to figure out how to mod it. I will give you a hint: I used Borland Turbo C 2.01 and Borland Turbo Assembler 4.1 This is no easy task. In fact, I recommend taking years to understand. Some people can understand it faster and you are better than me. In fact, it took me 41 years

For those of you who just want to put your own picture in and move it around, just use a bitmap editor like Paint in Windows XP which is free! Please make sure it is in uncompressed form using 256 color bitmap formats when you save it.

Thank you to real mom and dad who brings their kids up to be successful in their career choice#!! Remember, a career is what you plan to do forever. A job is what you do to get by. I heard someone told me JOB stands for "Just Over Broke hehe".

Honour to my real dad Nguyen Binh Thuy and real mom Huong Thi Vu who put me through school so I am successful in my job of choice. Thank you God for blessing my mom at least with enough to live a happy life out from now until you call her home at 100 years old. hehe
